DUST-TANK.

'Applieation filed October 13, 1909. Serial No. 522,460.

To. all-whom'it may concern Be it known that I, J AMEs C. L wIs, residing at Mansfield, in the county of Rich land and State of Ohio, have invented a new and Improved Dust-Tank, of which the-following is a. specification. V

This invention, in its generic nature, re-

lates to improvements in that class of apparatus or means for cleaning carpets, draperies, etc;,' by compressed air, known as portable vacuumcleaners, and in 1ts more *specific'nature, it'has for its object to proyide an improved'construction of the tank proved construction oftank. Fig. 2, is a vertical section'thereof. Fig. 3, 1s ,a view .-fffoi -ireceivingfthe dust, especially designed .15

for takingnp the fine dust in such manner thatii: Willnot injure or clog the hood and- .readily pass 'ofi, so that the necessity of takingthe tank apart for cleaning the hood is overcome.

With other objects in view that will be hereinafter made clear, my invention embodies the peculiar combination and novel arrangement of parts, allof which will be hereinafter fully described, specifically pointed out in the claim and illustrated in the accompanying drawings, in which Figure 1, isa perspective view of my imperspectivfof the flange and rim ends of theupper' and lower drum sections, the

14 and set screws 14 the door being'provided for readily cleaning out the tank.

At a suitable point below the annular Y flanges 1, crossed brace rods 6-43 are horizontally held within the shell and to the said braces is fixedly held, in any approvedman nor, an inverted dust pan 7 against which in turn are of suitable length, and in practicetare equipped with pick up or suction nozzles (no-t shown) of any approved type.

By reason'of arranging the dust pan in the shell so,the inle t tubes 8--8 discharge d rectlyagainstthe said pan 7, the heavy dlrt will strike against the said pan and be deflected back onto the bottom of the tank.

In my present type of tank, I have also pro vided a novel way for holding and securing the hood, which forms an essential feature of my present invention. In my construct-ion, .the hood or dust separator' 5 is of canvas or other straining ma-- terialand is'preferably cone-shaped with itsthe inlet tubes 88' discharge, hose members 1616b'e1ng attached to the tubes which upper end formed into an annular rim 5O thatis clamped between the flanges 3 of the rim members 4 and secured by the bolts. 43 that pass through the apertures 42 of the two flanges m, as clearly shown in the draw- For bracing the hood or separator and holding it from being drawn upwardly by the'suction, a V.-shaped skeleton frame 17 is attached to the innerwall of the upper shell section and projects down into the other section to hold theseparator or hood with its apex end in close proximity to the retarding or deflector pan 7. v

From the foregoing taken in connection with the drawing the complete'arrangement and construction of my tank will be apparent.

By arranging the inverted dust pan directly over the tubes 88 as-shown, the

em use. Another and important advantage of the'pan construction is that it prevents the heavy dirt-fromstriking the hood, and

since the fine dust does not hurl; or clog it up, there is no need of taking-the tank apart to clean the hood.-

. Having thus described my invention what I claim is:

In a suction cleaning apparatus, a dust tank having a removable top. section, 21'

skeleton frame composed ofV-sheped members secured to the top sectlon and projected into the lower sectlon, a filtering hood (lopies of this eaten: may be obaeinefl for five held over saicl frame with its edges clamped between the top amlbottom sections of-the tank, across bar frame directly beneath said hood, an lnverted pan secured to send cross bar frame and having 21 depending annular Jnssn E.
